IPC: G06V10/46
Filed: 1986-05-29
Abstract: A practical vision system for controlling the positioning of 
a robot arm recognises and locates objects. The vision system 
(20, 30) processes binary images, but recognises objects 
based on boundary features such as lines, arcs, corners and 
holes instead of "blob features" such as area and best-fit 
ellipse. Consequently, the vision system can process two 
common situations not handled by blob analysis: merged 
blobs due to touching or overlapping parts and incomplete 
blobs due to low image contrast. The microprocessor-based 
system is interfaced to the robot system and can recognize up 
to five parts per second.
